i need to send e-mail's from the iis 6 via smtp server that are 2 diferent machines
i have this exampel but is not working
Public Sub SendMail(ByVal from As String, ByVal [to] As String, ByVal subject As String, ByVal body As String)
Dim mailClient As New SmtpClient(test.MailServer)
[Code]....
I'm using the TcpClient and TcpListener classes to read/write to the network when a request comes in on port 25. All I'm trying to do at the moment is make it so that my server program can receive SMTP messages from other SMTP servers. I've tested in Telnet - if I connect to my own IP on port 25 and type EHLO, MAIL FROM, RCPT TO, DATA etc then all works as it should and the details I entered are logged by the program (it doesnt do anything about delivering these details/email yet).all looks good... but then when I try and just send an email to my domain from my work account I can see that a connection is made to my program and the string "EHLO workdomain.com " is received by my program - my program responds to the remote SMTP server with "250-mydomain.com Hello" and then a CrLF and then "250-OK". After that point however, my app does not receive anything further at all from the server at work. I'm guessing I am doing something wrong with the data I'm returning when it sends EHLO but can anyone point me in the correct direction?
I was using telnet to test with, it seems that I have made it work only with telnet.In telnet each time I type a key the data is passed to the server, however with a real SMTP server it just sends each entire command in one go. So after altering my server a little I can now get it to respond with the 250-OK which I thought it already was doing.. but it still doesnt work. The remote server just sends EHLO and then thats it nothing more.Something interesting, at the moment I am ending all of my responses to the remote server with VbLf - if I change this to VbCrLf (which is what I believe it is meant to be according to the SMTP standard) then I get an infinite amount of empty strings sent to my program (or perhaps some other character that just shows as an empty string in intellisense when stepping through the code). Changing it back to just vbLf or ControlChars.Lf makes it go back to just sending EHLO and then nothing else..
as topic, i need to send an e-mail without outgoing authentication becouse server hasn't outgoing authentication.. how i can do this??
View 1 RepliesI'm using the following code to send an email from my vb.net web application.
Public Function SendMail(ByVal strTo As String, ByVal strFrom As String, _
ByVal strSubject As String, ByVal strBody As String) As String
Try
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Credentials = New _
[Code] .....
It works fine when I use my personal live.co.uk email address as the strFrom value, or even a made-up email address. But when I use a different one (contact@mydomain.com), which is perfectly valid and working, I get the following error:
"The SMTP server requires a secure connection or the client was not authenticated. The server response was: SMTP authentication is required."
How can I send an Email with VB.2008, is the SMTP server needs autentication???
I can do it without autentication, mas with that, it doesnt work
This emailing code wont seem to work in my program. I get an exception "The SMTP server requires a secure connection or the client was not authenticated. The server response was 5.5.1 authentication required."

I don't really know how to code but am pretty good at tweaking. I'm trying to set up a script that I can run to delete a single file, multiple files, a folder or multiple folders on a list of servers.I was thinking that the script could read the files to be deleted from a .txt file and apply the deletion to a list of servers in another .txt file.Example:
FilesToBeDeleted.txt:
\(insert_server_name_from_list)c$Program FilesBINexample_file.rpt

I have a list of functions that I'm using throughout my .net application. Is there a way that I can include a file into the pages that require the functions without having to copy and paste the functions to each individual page?
The large majority of pages I've found on MSDN are either toward people who are already familiar with .net to those who have never programmed before and just starting. I haven't been able to find one for people who are versed in programming and just need a list of functions and methods.
I'm trying to add a handler, but as soon as I'm targetting a method that has parameters, the handler fails. This is the simple code:

Never before did i realize the neccessity to scrap the User Account Control, other than for reasons it was simply annoying, until i became a developer. I have an application that does nothing more than remove and create files within its own directory. Are you telling me every application that creates local files require admin rights? Surely something is wrong here. Can this not be circumvented? How do other developers overcome this issue?

If I wrote some software that used an access database to store data. If I then gave the code to a third party, who ran this sofware on his Pc. Would the code work , if his Pc did not have the access database installed.I read in some article that this would still work? If this is true, how could this work? If the above software had an form which required the client to input details of an order. When the order details were being processed by the code where would it store them if no access database was installed on that pc.

View 26 RepliesI've stumbled upon this code:
var knownSeparators = new[] { "\", "/", "|", "." };
return knownSeparators.FirstOrDefault(path.Contains);
where path is a string and the return value should be a string as well.
Allthough path.Contains' intellisense suggests a parameter, it works fine without one.
How does this work exactly? Is there any way to copy this behavior in vb.net?

Is there any way to use VB 2008 to create an app to work on a computer that does not require .NET 2.0+? If there is no way to install .NET on the target computer, is there any way to write the app in such a way that it works on the computer?
View 12 RepliesI have an application written in VS2010 that targets FW2.0..It has no dependencies other than the framework.The application runs fine on the local drive.But one user tells me that he already had FW2.0 installed but had to install FW2.0 SP2 in order to get the exe to run if it was placed on a network/shared folder? Why would running from a server/shared folder make the application crash if Sp2 wasn't installed? some network/path error that was was fixed in SP2 that doesn't affect the app when running off the local C drive ?

I'm in a VB.NET application. I have referenced some java.* namespaces in my file and am utilizing objects and methods from this namespace throughout the code. Presumably this is relying upon J# to compile.
Imports java.util
Imports java.util.zip
Imports java.io
Are these JDK namespaces fully contained in the .NET framework, or will my clients need to have Java installed when they go to run my application?As a side note, I have not explicity referenced any external Java DLL's or anything. This is all pure .NET as far as my code is concerned.
I made a little program for Hobby-use, and I like it to be installed by an installer. There's an installer program (Windows Installer 3.1?) deliverd with Visual Studio 2008 but that does not do the job completely. I want a coupling to be made between a program and a the users startup directory.If Windows Installer 3.1 can do that after all, can somebody explain how? If not, is there a free or low cost, simple to use (no scripting) installer program what will do the job? At last: Is there a version of .NET Framework 3.5 that does not require downloading during the user's setup procedure?

View 5 RepliesI'm not sure that I'm doing the right thing here..I'm writing a user control that's supposed to be (fairly) generic. It's a bit like a modified email client specifically tailored to some of the internal things we do.
The view is composed of two main pieces, a message list and a viewer. I need this viewer to be interchangeable, so if someone wants a different style of view they can simply handle an event and change a property. My original idea was to just have an INoteViewer, but since I'm adding it to my form I also need to guarantee that this object is a Windows.Forms.Control of some sort.
Should I continue along these lines and maybe raise an ArgumentException if I can't cast it to INoteViewer, or should I go a different direction and create a class that inherits from Windows.Forms.Control?
